The original version of this article unfortunately contained a mistake. The first sentence under the sub-heading “Cell culture and MTT assay for cell viability” is incorrect. The corrected sentence is given below, “Three human cancer cell lines namely K562 (Leukemia), WRL68 (hepatic) and MCF-7 (breast) obtained from National Centre for Cell Science (NCCS), Pune, India were cultured and maintained at CSIR-CIMAP, Lucknow. The cell lines were cultured in DMEM/Ham’s F-12 medium containing 10% heat-inactivated FBS, 5 mg/mL of penicillin, 10 mg/mL of neomycin, and 5 mg/mL streptomycin.”
